Malwarebytes can also audit your device for potential security gaps and suggest remedies, and detects potentially malicious apps and software before you download them.

It aggregates local sales data in your area and lets you see the price of different items at various locations – so you can see when that TV you wanted is on sale, or make sure you're getting the best price on your groceries. You can also access printable coupons to save even more, and Favado's editors will identify the best sales each week to give you some recommendations.

What’s it about? From the developer behind Angry Birds, Bad Piggies puts players in control of those evil green pigs, tasking them with building machines to get the pigs where they need to go.

What’s cool? Your mission in Bad Piggies is to build stuff. With a pile of items like wheels, axles, platforms and more, you need to build things like carts and cars to carry your pigs to the end of each level, without them crashing and smashing their rides. Each level provides a different challenge and different tools with which to build your vehicle, including things like soda-powered jets, engines, wings and more. Bad Piggies already packs more than 100 levels, and developer Rovio Mobile has just added 30 Halloween-themed challenges for players to work through as well.

Who’s it for? Fans who like physics-based games with a touch of engineering should check out what Bad Piggies has to offer.
